e64e28917cb47d06b9f3b0ba24989805bd4ee1ad [Site Isolation] The monochrome media feature always evaluates to 0 in cross-site iframes
not a security fix
confidence 0.12
signal score 6.3
Source/WebCore/css
Classified as not security-relevant.
Triage note: monochromeFeatureSchema switches from document->localMainFrame() to frame->mainFrame().virtualView(), so the query resolves under Site Isolation when the main frame is remote. Correctness/plumbing refactor, not a security fix.
This commit was flagged by the signal scorer and reviewed by AI (not a human). It is listed only so the triage is auditable; there is no root-cause analysis because this is not a vulnerability fix.
